My research focus for many years was diversity curves, speciation, and extinction, with most of my publications being about Cenozoic North American mammals or (under duress) Phanerozoic marine invertebrates.
But I have finally seen the light at the end of the Phanerozoic and turned my attention to quantifying diversity and extinction at this very moment.

My latest greatest inspirations are the gap filler turnover rate equations, the creeping-shadow-of-a-doubt Bayesian extinction probability equation (say that a few times fast), the rescaled Forbes index, shortest bridges, the switchoff equation, and the double geometric distribution. Much of which is top secret. But before that came shareholder quorum subsampling, which at the moment is functionally still a secret despite having been described in three different papers. Try running it on your ecological count data with this simple R function - if you dare. And for the more ambitious, there's always the option of downloading the fossil record of everything and crunching it to smithereens with the Fossilworks built-in diversity curve generator.

I also have projects concerning contemporary extinction rates, empirical abundance distributions, body mass estimation, Quaternary megafaunal extinctions, zoo finances, and, wow, at this point I'm starting to lose track of it all.
Not to mention that oh so many years ago I worked way too hard on quantitative methods of time scale construction.

If that's not enough, my CV gives all the gory details.
